SPECIFICATION forming part of Letters Patent No. 359,460, dated March 15, 1887...

' Application filed December 8, 1886. Serial No. 220,594. (No model.)

To all whom, it may concern-.-

Be it known that 1, ANDREW .T. NnLsoN, a citizen of the United States, residing at Moline,

' in the county of Rock Island and State of Illinois, have inventedcertain new and useful Improvements in Oultivators, of which the following is a specification.

My invention relates to that class of wheelcultivatorsin which the draft plates or bars are hinged to the axle and the wheels journaled on spindles which are fixed to the draftbars in such manner that the wheels swing with the draft-bars to permit either wheel to advance and remain parallel with the other I 5 wheel and with the line of progression of the cultivator, while the axle or connecting-yoke is thus brought obliquely to the path or line of progression, and in which the forward ends of the draft-bars are connected by a yoke-bar hinged to said draft-bars, and which, while it permits either draft-bar to be advanced relatively to the other, at the same time produces simultaneous movements of said draft-bars;

and the main feature of my invention consists in a tongue or pole pivoted to the axle at its rear end in such manner as to permit either wheel to advance relatively to the other wheel without moving the tongue laterally in any manner, and connected and pivoted to the yoke which connects the forward ends of the draftbars in'such manner as not to interfere with either wheel advancing relatively to the other, while at the same time both wheels will be swung or deflected laterally simultaneously by lateral movement or swing of the tongue.

My invention consists, further, in its main feature in forming said tongue in two parts and pivoting its forward and longer part to its shorter and rear end, to permit deflecting the wheels laterally without moving or affecting the tongue and to permit swinging or de fleeting the tonguelaterally at its forward end without affecting the wheels, while also permitting either wheel to advance relatively to ally in any manner. Means are provided whereby the front and rear parts of the tongue may be locked to each other to secure the principles of action first described, and may be 5 freed so as to permit lateral flexurc at the the other without moving the tongue later-.

hinge which unites them, to secure the principles of action last described; and the tongue, while used in either manner, will at all times act as a support for the axle.

The invention further consists in constructions and combinations hereinafter described and claimed.

In the accompanying drawings, which illustrate one method of applying my invention, Figure l is a top plan of a cultivator of the type hereinbefore described in general terms with my invention applied thereto, the tongue shown as partly broken away; Fig. 2, a side elevation; Fig. 3, a top plan showing the parts in different relative positions from that shown at Fig. 1; Fig. 4, a perspective showing parts of the cultivator. Figs. 5, 6, and 7 are elevations, partly in section, showing details hereinafter described.

Referring to the drawings by letter, the same letter indicating the same part in the different figures, A represents the central part of the axle, and may be formed as shown or of frame-work, or in any other ordinary or desired manner which will provide an elevated 7 5 central part, a, side parts, a, and ends a, to which ends the plow-gangs B B are hingedone to each end a.

The gangs B may be of any ordinary construction, and are provided with ordinary cultivating-shovels, b, and handles 1). The gangs are coupled to the axle as follows: Aplate, C, (see Fig. 7,) is bolted to the forward end of each gang, from which an arm, 0, extends upward and forward and an arm, 0, extends 5 downward and forward. The forward ends of the arms 0' 0" have holes through which a bolt,

61, passes, on which bolt the arms are thus journaled or hinged to permit swinging the gangs laterally at their rear ends. The bolt 9 (1 passes lengthwise of and through a plate, D,

and the plate D has atransverse groove, (1, in

one side which rests against a sleeve, d,which sleeve is mounted loosely on the end a of the axle. The shank ends of a clip-plate, 11', pass through the plate D to one side of the bolt (1, and nuts d. on said shanks hold the plate D firmly to the sleeve (1, while the sleeve can turn freely on the spindle a to permit of ver- This joint, Ico

tical swing of the plow-gangs.

while simple, is very effective in permitting the necessary movement of the gangs with great freedom, while the length of the bar D and other construct-ions will hold the gangs steady against wabbling motion, and thus pre- Vent any binding in the joints which would interfere with the necessary movements and easy manipulation of the gangs in operation.

The draftbars E are each formed of two bars, 6 e, converging at their forward ends, where they carry a draft-clevis, 0, provided with a series of holes, 0. A. bolt, f, passes through the rear ends of each pair of bars 0 and lengthwise of and through a bar, F. The end a of the axle passes through the bar F and is fixed thereto by a pin,f. The draftbars are hinged to and swing freely laterally on the bolt f. The bars F serve, also, to hold the sleeve (1 in place on the axle parts a. A side elevation of the draft-bar is shown at Fig. 6 of the drawings, and a sectional plan in line mm of same figure shown at Fig. 5, both of which figures also show other parts in section and others in elevation.

The draft-bars E are adjustably mounted on the wheels G G as follows: Each draft-bar has twovertical bars, 9 g, fixed thereto, as shown at Fig. 6, or in any other suitable manner. Each wheel G is journaled 011 a stub-axle, g, which is secured or fixed in any suitable manner to a clamp-plate, g, which is fitted against one side of the bars y, and the inner end of the stub-axle is extended and screw-threaded and carries another clanipplate, g', and a nut, g. The clamp-plates can be adjusted higher or lower on the bars 9 and held after adjustment by the nut 51 for the purpose of adjusting the height of the parts a of the axle, to which the plow-gangs are secured, and thereby regulating the depth of cultivation by the cultivator-shovels.

H are the hang-up hooks, secured to the vertical parts of the axle by clips 71, and adapted to engage with and suspend the gangs in an ordinary manner, as shown by dotted lines at Fig. 2, for the purpose of suspending the gangs and carrying them on their own wheels G. The upper and forward end, H, of each hook-bar H is extended laterally and approximately in line with the part a of the axle to form a bar, to which the upper and forward end of the lifting-spring I is secured, its lower end being provided with a chain, 1, which is engaged with a hook, 2', which is fixed to the plow-gang. The spring I has a hook, t", which can be engaged with either of a series of notches, h, in the bar H, to adjust the spring in line with the gang to suit different lateral adjustments of the gangs 011 the sleeves d, made to adjust the distances between the gangs to adapt the cultivator for use in cornrows planted at different distances apart.

J is the yoke connecting the forward ends of the draft-bars E. The upper part of the yoke J is formed of two bars, J J, arranged the one above the other, and its vertical parts are formed of bars or rodsj, bent at their lower ends and extended upward to the bars J J, to which they are fixed to form braces j for the vertical parts j. Each vertical part j at its lower end passes loosely through a forward end of the draft-plate E, to form a hinge-connection therewith, and a keeper, j, holds the parts in place, while permitting the necessary hinge movement.

K is the tongue, formed in two parts, K K", the front part, K, consisting of a single bar, the rear end of which passes through between the bars J J, and the rear part, K, consist ing of two bars, 7s 7r, hinged by a bolt, 76, at their rear ends to the part a of the axle, in such manner that they can swing laterally at their forward ends on said bolt as a pivot. The bars It" may be strengthened, if desired, by a spool and bolt, 7t, of ordinary construction. The forward ends of the bars k extend forward of the bars J J, the one above and the other below said bars, and are pivoted or hinged at their forward ends to said bars J J by a bolt, Z, which bolt Z also passes through the forward part, K, of the tongue, and forms a pivot or hinge between the forward part, K, of the tongue and its rear part, K. The bolt 1 also passes through the forward ends of brace links or barsL L, one of which extends laterally and rearwardly from each side of the tongue to the bars J J, and are j ournaled or hinged at their rear ends to said bars by means of holes in their ends,which receive the upper extended ends of the brace-rodsj. Any other means of hinging the links L to the bars J J would answer the same purpose. The rear end of the part K of the tongue has a hole, at, coincident with holes in in the bars 7c 74:, through which a pin, m,may be inserted to lock the front and rear parts of the tongue to each other, when desired, and in such manner that both parts K K will swing together as a rigid tongue on the pivot-bolt k. The bolt or pin m is attached by a short chain, 121/, to the bars 7:, and when not in use, as last described, will hang convenient and ready for use when required.

\Vhen the cultivator is in operation, either wheel G and its adjacent end of the axle A and the plow-gang at that end of the axle can be advanced relatively to the other wheel, and the other end of the axle and its plow-gang, by an advance movement of the draft-bar in the manner common to the hereinbefore'described type of cultivator, and as shown at Fig. l by dotted lines and at Fig. 3 by full lines. Vhen this relative movement of the parts takes place in cultivators of this type as heretofore constructed, the tongue will be moved laterally, and more or less interfere with the draft-animals and the operation of the cultivator. By reference to Fig. 1 it will be seen that when such movement takes place in my improved cultivator the tongue is not moved laterally, as the bars or links L swing on their pivoted forward ends and permit the yoke J to move laterally without moving the tongue, and this is the case, the same when the pin m is in place to make the two parts I ally;

the pin m is in vplace and theforward and rear ends of the tongue are thus rigidly connected, either wheel may be advanced, as last described, without moving the tongue laterbut whenthe tongue is moved laterally it will swing both wheels with it, and thus facilitate turning the cultivator. This operation arises from'the fact that the draft-bars are connected by the yoke J and swing simultaneously with the endwise movement of the yoke, and said yoke is moved laterally by the lateral movement of the bolt l, which connects the links L to the tongue, and the bolt Z is moved laterally by the lateral movement of made free to swing on thepivot-bolt I,

the tongue. In all of-these movements, with the joint between the two parts of the tongue rigid, the tongue swings on its pivotal connection with the axle A, and the tongue sustains the axle principally by reason of the bars It is sustaining the yoke J, and thereby sustaining the forward ends of the draft-bars, which hold the axle upright and in Working position at all times, and especially when the plows are suspended on the carrying-hooks;

When the pin m is removed and thetongue its front part being free to swing laterally independently of its rear part, as shown at Fig. 3, in which the line of progression is shown by the line WV WV, then again either wheel may advance relatively to the other wheel, as shown at same figure, without moving the pivot-point Z laterally, and the forward part of the tongue may be swung on the pivot-bolt Z, as shown at same figure, in turning at the ends of rows,

and may swing in a similar manner when the cultivator is moving along in ordinary operation, to prevent the lateral swaying ot' the draft-animals affecting the operations of the cultivator. When the tongue is free, as last described, the slight laterally-swinging movement of the wheels which is constantly occurring in operation, will not affect the tongue, and hence it will not be almost constantly forcing the neck-yoke alternately against or toward the draftanimals.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
